The scanning tunnelling microscope (STM) relies on localized electron tunnelling between a
sharp probe tip and a conducting sample to attain atomic-scale spatial resolution. In the 25 …

Conventional scanning tunneling microscopy (STM) is limited to a bandwidth of a few kHz
around DC. Here, we develop, build, and test a novel amplifier circuit capable of measuring …

THE invention of the scanning tunnelling microscope1 (STM) has stimulated the
development of several new forms of probe microscopy2–10. Here we demonstrate the use …

The alternating current scanning tunneling microscope (ACSTM) extends the capabilities of
the STM from a simple atomic scale topographic and local density of states (LDOS) probe to …

We describe a fully ultra-high vacuum compatible scanning tunneling microscope (STM)
optimized for radio-frequency signals. It includes in-situ exchangeable tips adapted to high …

The design and performance of a cryogen-free low temperature scanning tunneling
